The granularity of the analysis is reexamined, and the information obtained from the moving images is efficiently compiled into a database. In the process, the possibility that this analysis can contribute to the reorganization of photographic materials that should have been used to verify the information is found.

We will report on the background, situation, and future issues from a different perspective than the local governments, institutions that publish archaeological site reports.
